EDWARD M. BECKMAN, OF G.A.RY, INDIANA.

v rnnumrm TIRE.

Application filed May 17,

To aZlw/wm it may concern:

Be it known that I, EDWARD M. BECKMAN, a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Pneumatic Tires, of

The 'present invention relates to {menmatic tires, and has for its object the provision of a novel and improved devlce or 1n- -sert to be used between the tire casing and thereof, and to also a 0rd a cushion between the inner tube and casingfor increasing the resiliency of the tire.

A further object is the provision of a bag or pocket of a cross section to fit between the tire casing and inner tube and filled with resilient members, which protect the inner tube from being punctured as well as adding to the resiliency and cushioning action of the tire. I

-A still further object is the rov-ision of such a device having provision or the insertion and removal of the resilient filler members, and means for protecting the inner tube. With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts.hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein the figure is a cross section of a pneumatic tire showcasing and tube. The bag or pocket has an.

outer wall 3 to snugly fit the inner surface of the casing, and has an inner wall 4 within which the tube? is fitted. Said bag or pocket can be constructed of leather, fabric or other suitable pliant or flexible material,

preferably of good quality to serve as a protection for the tube.- The edges of the walls 3' an d 4 are united, as at 5, and the space within the bag is filled with individual relatively-removable resilient members, which, as shown, are hollow rubber balls 6. These balls or members provide resiliency between the tube and casing, and also serve as a pro tection for the tube to prevent puncturing thereof. Nails, tacks, or other sharp pieces which may penetrate the casing 1 may puncture one or more of these balls 6, but this Wlll not make any appreciable reduction in pressure of the tire, and such filler balls or members will protect the tube from being" punctured, under almost all conditions. 'Fi1r thermore, the bag and its filler will not injure the casing or tube, and although the-..

cross sectional area of the tube when-inflated is reduced, the resiliency of the balls or members will give life to the tire.

In order that the balls 6 can be inserted i into the bag for st'uifing or filling same, and

9 of suitable pliant material are sewed or otherwise fastened to the wall 4 of the bag,

as at 10, and extend inwardly to overlap adjacent to the rim 11 between the opposite edges of the bag and easing 1, to project thetube 2. The flap 8 also closes the opening 7 to prevent the tube from expanding into the bag as might be injurious.

Having thus described the invention, what is claimed as new is 1. A tire protector and cushion comprising a bag to fit between the'tire casing "and inner tube, and a filler of individual rela tively -movable hollow resilient members within said bag.

I 2. A tire protector and cushion comprising a bag of a shape to fit between the tire casing and inner tube','and a filler of individual relatively-movable resilient members in :the bag.

3. A tire protector and cushioncomprising a bag of horseshoe-shaped cross section to fit between a tire casing and inner tube,

and a filler of individual relatively-movable I hollow resilient balls in said bag.

4. A tire protector comprising a bag to fit within a tire casing and inner tube, a filler in said bag, and a flap secured to the bag to extend beyond one edge thereof belocated between one of said edges and the corresponding flap to be closed by such flap.

6. A tire protector and cushion comprising a filler to be disposed between the inner tube and the tread of the casing including individual relatively-movable resilient members.

In testimony whereof I hereunto affix my signature.

EDWARD M. BECKMAN.
